WET SEPARATR FOB DUST-REMOVING APPARATUS.

Application led May 14, 1907.' Serial N0. 373,548.

21h all whom it may concern: e

Be it known that l, RALPH F. DrsnunNs, a citizen of the United States, residing at `:f-radford, in the county of i- McKean and y zitate of Pennsylvania, have invented 'certain new and useful Improvements in llVet `deparato'rs for Dust-'Removing Apparatus,

of which the following is alspecification.

.My invention relates to a dust removing apparatus and more particularly to that kind of an apparatus comprising a nozzle having a dust collecting inlet slot and means, as a suction pump, for creating a partial vacuum back of the inlet of the nozzle for il alle purpose of removing the dust laden air from the surface over which the nozzle is moved. l

In such an apparatus it is convenient to p lace a dust collector between the nozzle and site suction a paratus in order that the latier may not. e clogged up by the collected dust, and my invention relates to a novel and eilicient form of dust collector. Dust collectors for this purpose are of two kinds: lry collectors in which the dust laden air is introduce-d, and which is provided with means for pcrmittin the passage of the air, but retaining the w ole or greater part of fi'ne dust, and wet collectors provided with a .iquid chamber' and "means whereby a cur dust collector embodying ymy invention 1nA central vertical section, some of the parts lacing shown in elevation.

In the drawing, is a casing jpn'eferably made in three parts, secured together by bolts 11, or in anyr other suitable manner. "i'hese parts comprise a central cylinder 12, a conical bottom 13y and an imperforate cover 14.

The bottom is provided with means for tightly closing it, comprising a plate '15, au

encircling strip 16, vand a screw handle 17. .his .means of closure is of usual form and '"'f needs no special description. The casing is supported on legs 18 or other suitable form Patented Dee. 1a, 1909..

of support, so that it may be elevated above y the surface of the ground.

flhe conical bottom 13 is provided at a suitable point with an aperture outside of which is secured a branchvpipe 20 to which in turn is secured a fitting 21 and beyond it an air inlet vpi e 22 connected, either directly to the ust. collecting nozzle (not shown?, or to the air oulet of a dry'separator not shown);l 1f desired, Va float valve 23 of usual construction and secured to the side of the apparatus by a chain 24, or other suitable means, is provided automatically to close the air inlet against 'the backward flow of the water within the a paratus.

At the upper portion o the casing 12 and preferably near the top 14 .is a suitable v aperture to which is secured an air outlet' pipe 25 of any suitable form and construction and secured to the casing by .any suitable means, as for instance, a fastening rin 26.v

S ightly above thev central medial line of the apparatus there is arranged a-transverse baie plate 30 centrally apertured and provided with an upwardly extending pipe 31 open at its top. Depending from suitable points ou this baille plate are chains 32 reaching down below the usual water level and the purpose of which is to prevent the formation of large bubbles of dust laden air at such level. lt is presumedl that these chains exercise their peculiar effect of pre-l venting the formation of bubbles at or near the water level, partly, at least, by reason of the irregular' character of their surfaces. Moreover, being, in 'the form herein shown, suspended in a manner which permits them to swing under theV effects' of the air currents set up within the separator, they will by 1 such movement further act to bring up the bubbles.

Arranged intermediate the pipe 31 and.

the cover 14. is a detlcctor S5 in the form of an inverted cup, the top of which is impor forato and the sides 3G of which depend downward so as to surround the pipe 31 leaving between the outside of the pipe and the inside of the deflecto'r an annular 4space 37. The deiector is suitably supported from the inside of the casing by rods .3,85%38,

secured lo the easing andthe del'lecto'r byv -bolts or in any other suitable nia-nn'en'v The top of the pipe is preferably on av level with the upper part of the outlet pipe 25, and the bottom edge of the deflector 35 is preferably on a level with the lower partof the outlet pipe 25.

The manner of using the device is as follows The parts being assembled in the manner shown in the drawing a suction is Vcreated iii the outlet pipe 25 and this being communicated to the vinterior of the casing a partial vacuum is formed'therein. It will, of course, be understood that the device is previously l'led with water up to a .point indicated at 50 or thereabout. 'The suction-,being maintained within` the interior *j'ofthe'iapparatum the ball valve 23 is finally lifted fromiits seat against the pressure of vthe ywater thereon due to the gravity of the latter and the dust laden air begins to flow from the pipe22 through the elbow fitting 21 and pipe 20 into the apparatus beneath the Water level. As the air passes through the mass of water it breaks up into little currents and parts with its dust which remains in the water. Sometimes under the effect of the outward flowing .current large bubbles form in the water and are carried over into the outlet pipe 25. This is undesirable, because these bubbles usually carry dust with them and tend to choke up the apparatus. In order to prevent this, I provide the baffle plate 30 against which these bubbles-:will tend to splash and be deflected and broken :up inthe process, and I provide it -Witl1 a restricted aperture leading to the pipe 31 in order that the current of air may be restricted at that point. This increases the relative rapidity of movement of the air through the pipe 31 and causes the air carrying particles of water with it to dash against the lower side of the defiector 35 and to fall back into the mass of water, parting with most of its water in the form of spray. The

' current of air deprived thus of its dust and water passes downward over the edge of the pipe 31 into the annular space 37, and thence upward again to reach the entrance to 'the outlet pipe 25 whence it moves onward to the suction pump.

In practice I have found this device quite efficient and the obstacles placed in the-path of the current of air to be suoli as will effectuallyremove the dust and water therefrom before its exit from the apparatus. y

, If, for any reason, the suction ceases'to exert an influence upon the air in the appaf device is stopped and the plate 15 is removed to permit of the discharge from the apparatus of the impurities which have collected therein.

Areceptacle in the lower part thereof, an air inlet below the water level, an air outlet above the water level, and an apertured baiiie disk arranged intermediate the air inlet and outlet and above the water receptacle, said baflle disk being provided With'an annular flange surrounding its aperture and extending upwardly above the level of the air outlet.

2. A separator for a dust removing appatus, comprising a casing having a water receptacle in the lowerpart thereof, an air inlet below the water level and a chain eX- tending to a point below the water level and adapted to prevent the formation of large bubbles atV- or near the water level.
